Nijmegen, Netherlands 'Filed Feb. 3, 1966, Ser. No. 524,935 Claims priority, application Netherlands, Feb. 23, 1965, 6502234 4 Claims. (Cl. 249-144) The invention relates to a mold for casting rectangular case-shaped or box-shaped bodies from a hardening mass such as mortar, the distance between the inner walls and/0r between the outer walls of the mold bein-g adjustable.

The invention has for its object to provide a mold of this kind which, when erecting flats may be used for casting a whole dwelling or an apartment thereof and in which the casted wall at one or both sides may obtain an additional layer, so that the casting takes place in stages.

According to the invention corner bars are located at the corners between the adjustable walls of the mold, said bars having `a part for the shortest distance and a part for the largest distance between the walls of the mold. Said combined corner bars have the advantage, that they are stiff and therefore do not bend when they are moved between the meeting walls of the mold and provide an eicient seal in the corner between said walls. In order to enable the bars to be moved with the desired part between the end edges of the meeting walls in the corners of the mold, said bars preferably are rotatable about a longitudinal axis.

The invention will be further described with reference to the accompanying drawing illustrating an embodiment of a mold according to the invention. In the drawing:

FIG. 1 is a sectional elevation of a mold for a dwelling and FIG. 2 is a horizontal sectional view taken along the line II-III in FIG. 1.

FIGS. 3 and 4 show on enlarged scale a corner bar in horizontal sectional view for the corner at the inner wall of the mold in two different positions.

FIGS. 5 and 6 show in similar manner as FIGS. 3 and 4 a horizontal sectional view of a corner bar for the corner at the outer wall of the mold.

The mold shown on the drawing has adjustable inner walls for the various apartments of the dwelling and said walls 1 are enclosed by common outer walls 2, which also may be adjustable. The walls 1, 2 of the mold by means of hinged rods 3 are carried by a frame 6 which by means of lifting cables 7 is suspended from a frame 4 supported on columns 5.

The walls 1, 2 of the mold at the lower Vend are closed by a bottom plate 8 and the pairs of opposite elements of the inner wall of the mold are connected with each other 'by horizontal struts 9, which each comprise a jack 10 for extending and shortening the struts.

As appears from FIG. 3 a corner bar 11 is moved between the meeting walls 1 of the mold, said bar being rotatable about a longitudinal axis 12 guided in a slot 13. For simplifying the drawing said corner bars are not shown in FIG. 2. In the position shown in FIG. 3 the oblique faces 14 provided at the bar 11 are lying in alignment with the outer faces 15 of the adjacent wall elements 1 and the bar with its sides -16 is lying against the end edges 17 of the wall elements.

In FIG. 4 the corner bar 11 is shown in the position in which it is rotated through an angle of about its axis 12 after having been removed out of the comer between the wall elements. For pouring .a layer of mortar 20 at the inner side of the casted wall in the mold the bar 11 may now be moved between the end edges 17 of the wall elements 1, whereby the oblique faces 19 of the bar are located in alignment with the outer faces 15 of the elements 1 and the sides 18 of the bar are lying against the and edges 17 of the elements 1.

The corner bar 21 of the corner between the outer walls 2 of the mold shown in FIGS. 5 and 6 is rotatable about a longitudinal axis 22 adapted to be moved in a slot 13. In the position shown in FIG. 5 the oblique faces 23 of the bar are lying in alignment with the inner faces 24 of the wall elements 2 and the sides 25 of the bar are lying against the end edges 17 of the wall elements 2. After the wall has been cast in the mold and has suiciently been hardened the wall elements 2 of the mold and the bar 21 are moved into the position shown in FIG. 6 and the bar is rotated through an angle of 180 about its axis 22 whereafter the bar is m-oved again between the end edges 17 of the wall elements 2. In said position of the bar 21 the faces 26 are lying against the end edges 17 of the wall elements 2 and the oblique faces 27 of the bar are in alignment with the inner faces 24 of the elements 2 whereafter an outer layer may be cast on the previously cast wall. In said position, projecting tongues 29 of the bar lie against the outer side of the wall elements 2, so that an efficient seal at the corner of the moldl is secured.

The bar 11 or 21 may be provided with a tongue 28 which in the position according to FIG. 4 or 6 is moved with the bar into the cavity of the mold and thereby constitutes a separation at the corner between the casted layers, so that a different mortar may be used for said layers. Said tongue 28 may also extend at the corner of the mold throughout the whole width of the cavity.

The bars 11 and 21 shown in the drawing are symmetric With respect to the bisectrix of the angle between the adjacent wall elements, but said bars may also be asymmetric for obtaining layers of different thickness, meeting in the corner of the mold.

What I claim is:

1. A mold for casting bodies having angularly disposed portions comprising, spaced inner and outer mold lforms each including at least two angularly disposed panels, the panels of at least one of said mold forms being independent of each other and separated at the apex of the angle formed thereby, and a corner bar removably positioned -between the adjacent ends of said independent panels, said bar including a plurality of parts of different widths to be selectively positioned between said adjacent panel ends to selectively space said inner -and outer mold forms, each of said parts including two angularly disposed surfaces at its portion remote from the Ibar and when the respective lpart is -disposed between said panel ends said angularly disposed surfaces are contiguous with the mold surfaces of the panels and completes the angular surface therebetween.

2. A mold as claimed in claim 1, wherein said inner mold form is separable, the corner bar being rotatable about a longitudinal axis, said bar having two said parts each including a pair of side faces adapted to lie against the end edges of said panels.

3. A mold as claimed in claim 1, wherein said outer mold form is separable, the corner bar being adjustable about a longitudinal axis, said bar having two said parts each including a pair of side faces adapted to lie against the end edges of said panels.

4. A mold as claimed in claim 1, wherein at least one of the corner ybar parts are provided with a thin tongue extending in longitudinal direction of the bar from the apex of said angularly disposed surfaces and projecting 4 l during the active position of the bar into the cavity of the mold. A'
